Virtual blaster

ABSTRACT

Embodiments provide techniques for automating control of electronic device. A first interactive game playing within the physical environment using one or more electronic devices is detected. Embodiments collect electromyogram data from one or more electromyography sensors within the physical environment and analyze the electromyogram data collected to determine muscle activations made by the user. Upon determining that the determined muscle activations made by the user match a predefined pattern of electromyography data, embodiments determine a gameplay action corresponding to the predefined pattern of electromyography data and transmit an instruction, to at least one of the one or more electronic devices within the physical environment, instructing the electronic device to perform the determined gameplay action.

BACKGROUND Field of the Invention

The present invention generally relates to entertainment systems, and more specifically to techniques for controlling an augmented reality game by tracking user muscle movements.

Description of the Related Art

Computer graphics technology has come a long way since video games were first developed. Relatively inexpensive 3D graphics engines now provide nearly photo-realistic interactive game play on hand-held video game, home video game and personal computer hardware platforms costing only a few hundred dollars. These video game systems typically include a hand-held controller, game controller, or, in the case of a hand-held video game platform, an integrated controller. A user interacts with the controller to send commands or other instructions to the video game system to control a video game or other simulation. For example, the controller may include a joystick and buttons operated by the user.

While video games allow the user to interact directly with the video game system, such interactions primarily influence the graphical depiction shown on the video game device (or on a connected display), and rarely influence any other objects outside of the virtual world. That is, a user may specify an input to the video game system, indicating that the user's avatar should perform a jump action, and in response the video game system could display the user's avatar jumping. However, such interactions are typically limited to the virtual world, and any interactions outside the virtual world are limited (e.g., a hand-held gaming device could vibrate when certain actions occur).

Modern technologies such as augmented reality devices enable game developers to create games that exist outside of traditional video game platforms (e.g., where the virtual world is solely output through a display device). Using such technologies, virtual characters and other virtual objects can be made to appear as if they are present within the physical world. In such augmented reality experiences, it is generally preferable for the virtual character to be rendered with realistic dimensions and positioning, in order to enhance the illusion that the characters are truly present within the physical world.

SUMMARY

Embodiments provide a method, non-transitory computer readable medium and system for automating electronic devices. The method, non-transitory computer readable medium and system include detecting a first interactive game is playing within the physical environment using one or more electronic devices. The method, non-transitory computer readable medium and system also include collecting electromyogram data from one or more electromyography sensors within the physical environment. Additionally, the method, non-transitory computer readable medium and system include analyzing the electromyogram data collected by the one or more electromyography sensors to determine muscle activations made by the user. Upon determining that the determined muscle activations made by the user match a predefined pattern of electromyography data, the method, non-transitory computer readable medium and system include determining a gameplay action corresponding to the predefined pattern of electromyography data and transmitting an instruction, to at least one of the one or more electronic devices within the physical environment, instructing the electronic device to perform the determined gameplay action.

DETAILED DESCRIPTION

Generally, embodiments described herein provide techniques for controlling devices in a synchronized fashion. Embodiments include determining one or more environmental devices are available within a physical environment. For instance, the environmental devices could include window covers, illumination devices, temperature control devices and the like. A first instance of audiovisual content that is playing within the physical environment is detected. Examples of audiovisual content include, without limitation, video content (e.g., streaming movie content), video game content and augmented reality game content. Embodiments determine an environmental condition at a first playback position within the first instance of audiovisual content. For instance, embodiments could analyze metadata for an instance of video content playing within the physical environment to determine that the video frames at a current playback position of the video content depict a dark and snowy arctic scene. Embodiments could then control the one or more environmental devices within the physical environment during playback of the first playback position within the first instance of audiovisual content, based on the determined environmental condition. For example, a temperature control device could be controlled in order to lower the temperature of the physical environment. As another example, embodiments could control one or more illumination devices within the physical environment to dim the level of illumination within the physical environment. Doing so enhances the user's experience during the playback of the audiovisual content.

Particular embodiments are described herein with respect to an immersive storytelling environment in which a story is played back through the interaction of storytelling devices (also referred to as interactive devices). More specifically, embodiments may use various storytelling devices, each capable of producing some auditory and/or visual effect, to create an immersive and interactive storytelling experience for a user. Such a system may include a variety of storytelling devices and a controller, connected via a network (e.g., an RF communications network). Each storytelling device generally represents any device capable of enhancing a storytelling experience, in response to user input (or some stimuli) a current context of a story. For instance, the controller device could configure the storytelling devices with stimulus and response information, based on a current context of a story. As an example, the controller device could configure a particular storytelling device to generate audiovisual messages responsive to a certain stimulus event (e.g., a user performing a particular action), and to perform another action responsive to other stimulus (e.g., the user not performing the particular action within a predefined window of time). Generally, the controller may be one of the plurality of storytelling devices, or the controller could be a standalone device (e.g., a computing device executing a control application).

Generally, each of the storytelling devices can have different capabilities in terms of audio output devices and audio processing and storage capabilities. For instance, a first device may include multiple higher quality speakers and a greater amount of audio processing and storage resources, while another storytelling device can include a relatively limited speaker and relatively limited audio processing and storage resources. This could be because, for instance, higher quality speakers, processing and storage resources are generally more expensive, and it can be desirable for economic reasons for certain storytelling devices to be lower cost devices.

As a result, certain audio effects may have a higher quality sound when played using the hardware of a particular storytelling device, relative to when the audio effect is played using another storytelling device with more limited hardware. As such, embodiments can tailor audio output during a storytelling experience such that that an optimal device is selected for particular sound effects during the story. For instance, a particular audio effect could represent a robotic assistant's voice giving instructions and updates to the player as part of the story. As the robotic assistant character is not represented by any of the storytelling devices used to play out the story, it could be thematically appropriate to output the audio effect representing the robotic assistant's voice through any of multiple storytelling devices used in the story. As such, embodiments could select one of the storytelling devices best suited to output the audio effect with the highest quality (e.g., the storytelling device having the speakers, processing and storage capabilities best suited for outputting the particular audio effect) and could instruct the selected device to output the audio effect. Moreover, such devices can be selected dynamically throughout the story, as devices may enter and exit the story playback for a variety of reasons (e.g., a new device is brought into the physical area where the story is being played out, a device runs out of battery power, etc.).

Additionally, in some cases the storytelling devices can be configured to work in unison to output a particular sound effect. For instance, a single sound effect could be output on multiple devices in unison in order to create a stereophonic or surround-sound experience for the user. In doing so, a slight time delay can be introduced in the playback of the sound effect across the multiple devices, to avoid phase cancellation between the sound effects being output by the devices. As another example, the devices can be configured to output the sound effect with a more significant time delay in order to create a particular auditory effect for the user. For example, in a story that simulates the user being within a bee hive, the various storytelling devices could each output the sound of a bee buzzing with a time delay in between the output of each of the devices, such that the sound of the bee buzzing appears to move throughout the physical environment. Thus, if the user is positioned between the various storytelling devices used in the playback of the story, the sound of the bee buzzing could appear to encircle the user, thus creating an immersive auditory experience for the user and enhancing the realism of the story.

Additionally, embodiments can include augmented reality devices together with various storytelling devices as part of an augmented reality gaming environment. As used herein, an augmented reality device refers to any device capable of displaying a real-time view of a physical, real-world environment while altering elements within the displayed view of the environment. As such, unlike a virtual reality device which displays a view of virtual world, an augmented reality device displays a view of the real world but augments elements using computer graphics technology. Such an augmented reality device may include a camera device (or multiple camera devices) used to capture a view of the real-world environment and may further include computer software and/or hardware configured to augment elements of the captured scene. For example, an augmented reality device could capture a series of images of a coffee cup sitting on top of a table, modify the series of images so that the coffee cup appears as an animated cartoon character and display the modified series of images in real-time to a user. As such, when the user looks at the augmented reality device, the user sees an augmented view of the physical real-world environment in which the user is located.

Additionally, the software could identify a first physical object within the visual scene captured by camera devices of the augmented reality device. For instance, embodiments could analyze the visual scene to determine the border edges of objects within the visual scene, and could use these border edges in order to identify one or more physical objects existing within the visual scene. Of note, as the captured visual scene represents a three-dimensional space (e.g., a physical environment captured using a camera of the augmented reality device), embodiments may be configured to estimate a three-dimensional space occupied by each of the physical objects within the captured scene. That is, the software could be configured to estimate the three-dimensional surfaces of physical objects within the captured scene.

In response to detecting a known physical object with the visual scene, the software could render one or more virtual characters based on the physical object's appearance within the captured frames. As an example, the augmented reality software could create a three-dimensional representation of the physical environment and could create a virtual object or character to insert within the three-dimensional representation. The software could position the created virtual object or character at a position within the three-dimensional scene, based on the depiction of the physical object within the captured frames. For example, the software could determine that the physical object is resting on a particular surface within the physical environment (e.g., a table surface, a floor, etc.), based on data about the size and shape of the physical object and the object's appearance within the captured frames. Upon identifying the physical surface, the software could position the virtual object or character within the three-dimensional scene, so that the virtual object or character is resting on the identified surface. Doing so creates a more realistic experience for the user.

Additionally, the software could scale the size of the virtual object or character based on the depiction of the physical object within the captured frames. For instance, the software could store predefined geometric data for the physical object, specifying a shape and dimensions of the physical object. The software could then use such information to determine how to size the virtual object or character in the three-dimensional scene. For example, assume the virtual object is a spherical object that is 12 inches in diameter. The software could determine a scaling for the virtual object based on the size of the physical object within the captured frames and the predefined geometric data specifying the physical object's known dimensions. As another example, the software could create a virtual character and could scale the size of the virtual character to life-size dimensions (e.g., the size of an average human being), using the size of the physical object within the captured frames and the predefined geometric data specifying the physical object's known dimensions. Doing so enables the augmented reality software to create a realistic and consistent depiction of the virtual object or character.

Generally, the augmented reality device can continue rendering frames of the three-dimensional scene interlaced with the frames captured by the camera sensors of the augmented reality device, in real-time, as the device (and the user of the device) moves throughout the physical environment. Advantageously, doing so provides a more immersive augmented reality experience for the user, as the user can paint the surfaces of objects within the augmented reality world and the user's painting will persist and remain accurate to the depicted physical environment, even when the environment is viewed from different perspectives using the augmented reality device.

An example will now be discussed with respect to FIG. 1, which illustrates a playtime environment in which a controller is instructing interactive devices to perform an effect, according to one embodiment described herein. As shown, the system 100 includes an action figure 110, a toy blaster rifle 115, an action figure 120, and a controller device 125. Here, the toys 110, 115 and 120 are generally capable of producing audiovisual effects (e.g., audio output, light effects, movement effects such as vibration, etc.). In one embodiment, the toys 110, 115 and 120 may be configured with an action disc device (e.g., device 200 shown in FIG. 2 and discussed in more detail below). Of note, while various examples are discussed herein with respect to the toy devices 110, 115 and 120, it is broadly contemplated that these techniques can be utilized with any number of devices and any types of devices, consistent with the functionality described herein.

However, while the toys 110, 115 and 120 are capable of producing audiovisual effects, the toys 110, 115 and 120 may not be configured with logic to determine when conditions in the physical environment indicate a particular effect should be performed. This may be due to, in part, the cost and complexity of configuring each toy 110, 115 and 120 with the logic and hardware resources to detect stimuli in the physical environment and to perform a contextually appropriate audiovisual effect in response synchronously with other devices. As such, the toys 110, 115 and 120 could be configured to receive commands (e.g., from controller 125) and to perform an audiovisual effect(s) responsive to the received commands. Doing so allows the toys 110, 115 and 120 to be produced much more economically, while maintaining the capability to perform audiovisual effect(s) as part of a storytelling or playtime experience.

For example, as part of a storytelling experience, the storyline could indicate that devices within the physical environment should play a particular sound effect when the user performs a predefined gesture to use the “force.” As such, the controller 125 could monitor the user's behavior to detect when the user has performed the predefined gesture. For example, the controller 125 could use one or more camera devices (e.g., within the controller devices 125, within one or more of the toys 110, 115 and 120, etc.) to monitor the user's movement within the physical environment. As another example, the user could wear an article (e.g., a bracelet) configured with an accelerometer device and capable of reporting data describing the user's movement to the controller device 125.

Upon detecting the user has performed the predefined gesture, the controller 125 could broadcast a command to the toy devices 110, 115 and 120, instructing the toy devices 110, 115 and 120 to synchronously perform an audiovisual effect. Such a command could be broadcast, for example, via a radio-frequency transmitter, an infrared emitter, an ultrasound transmitter, and so on. More generally, any communications protocol may be used for the communication between the controller and the toy devices 110, 115 and 120, consistent with the functionality described herein.

The toy devices 110, 115 and 120 could then receive the command and could perform the specified audiovisual effect in synchrony. For example, in the event the command specifies to play a particular sound effect, each of the toy devices 110, 115 and 120 could output the particular sound effect in synchrony with the other toy devices, thereby creating an improved sensorial experience for the user, relative to any of the toy devices 110, 115 and 120 playing the sound effect individually. Here, the sound effect could be, e.g., a sampled sound effect or a function-generated sound effect. Moreover, as discussed above, by playing the sound effect synchronously with one another, the toy devices 110, 115 and 120 can compensate for each other's weaknesses (e.g., a particular toy device being capable of outputting sounds within a limited frequency range), thereby producing an improved sound effect and sensorial immersion for the user.

While any number of toy devices can be used, the sense of immersion experienced by the user generally scales with the number of devices performing audiovisual effects in synchrony. For example, the controller 125 could detect when the user pulls the trigger to fire the blaster gun 115, and in response, could broadcast a command to all of the toy devices 110, 115 and 120 to output the sound effect of the blast being fired. Additionally, the controller 125 could instruct the toy devices 110, 115 and 120 to perform additional audiovisual effects, such as flashing lights and movements, in response to the user firing the blaster. Doing so helps to overload the user's senses, thereby creating a more immersive and realistic playtime experience.

Generally, a variety of techniques may be used to configure the toy devices 110, 115 and 120 to synchronously output the audiovisual effect. In one embodiment, the toy devices 110, 115 and 120 could be configured to output the audiovisual effect immediately upon receiving the command from the controller 125. Such an embodiment may be preferable when the toy devices 110, 115 and 120 receive the command at substantially the same time and when the toy devices 110, 115 and 120 take substantially the same amount of time to process the command and to perform the corresponding audiovisual effect. As another example, each of the toy devices 110, 115 and 120 (as well as the controller 125) could maintain an internal clock whose time is synchronized to the internal clock of the other toy devices, and the command transmitted by the controller 125 could specify a time at which to perform the audiovisual effect. Generally, any technique suitable for use in synchronizing the internal clocks may be used, consistent with the present disclosure. Examples of such techniques include, without limitation, Network Time Protocol (NTP), Precision Time Protocol (PTP), Reference Broadcast Time Synchronization, and so on.

Additionally, the controller 125 could be configured to selectively playback certain audio effects on the devices 110, 115 and 120, based on which device is best suited for the playback of each particular audio effect. For instance, a particular story could include audio effects representing dialogue from a robotic assistant, where the robotic assistant is not directly represented by any of the storytelling devices 110, 115 and 120 used in the playback of the story. As such, the controller 125 could select one of the storytelling devices 110, 115 and 120 that is best suited to output the audio effect with the highest quality sound. Thus, the controller 125 could determine that the toy blaster rifle 115 has the optimal speaker configuration and audio processing capabilities to output the sound effects representing the robotic assistant's dialogue and could transmit the corresponding audio data to the blaster rifle 115 for output.

Of note, the controller 125 can be configured to dynamically determine the optimal storytelling device(s) for outputting a particular sound effect, as the available storytelling devices can change from story to story and can even change within the playback of a single story. For example, during the playback of a particular story, the action figure 110 could run low on battery power and could be removed from the story as a result. As such, the controller 125 could remove the action figure 110 from consideration when subsequently placing audio effects. As another example, the user's friend could visit the user's house and could bring a fourth storytelling device into the playback of the story. As such, the controller 125 could consider the fourth storytelling device in addition to the devices 110, 115 and 120 when searching for an optimal device to output subsequent audio effects.

FIG. 2 illustrates an example storytelling environment, according to one embodiment. As shown, the environment 200 includes a cloud computing environment 210 and a home environment 225, interconnected via network 222. The home environment 225 includes two playgroups 230 ₁₋₂ of storytelling devices, as well as a user(s) 255 and a bridge device(s) 250. Here, the user may connect to the bridge device 250 via an application (e.g., executing on a mobile device, rendered within a web browser, etc.). The cloud computing environment 210 hosts a plurality of services 215 and a portal user interface 220.

Generally, cloud computing generally refers to the provision of scalable computing resources as a service over a network. More formally, cloud computing may be defined as a computing capability that provides an abstraction between the computing resource and its underlying technical architecture (e.g., servers, storage, networks), enabling convenient, on-demand network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort or service provider interaction. Thus, cloud computing allows a user to access virtual computing resources (e.g., storage, data, applications, and even complete virtualized computing systems) in “the cloud,” without regard for the underlying physical systems (or locations of those systems) used to provide the computing resources.

Typically, cloud computing resources are provided to a user on a pay-per-use basis, where users are charged only for the computing resources actually used (e.g. an amount of storage space consumed by a user or a number of virtualized systems instantiated by the user). A user can access any of the resources that reside in the cloud at any time, and from anywhere across the Internet. Doing so allows a user to access information and the services 215 from any computing system attached to a network connected to the cloud (e.g., the Internet).

Each playgroup 230 _(1-N) generally represents a set of storytelling devices involved in a unique storytelling or playtime experience. For instance, the playgroup 230 ₁ represents a science fiction-themed storytelling experience and includes a light sword storytelling device 235, an action figure controller storytelling device 240, and a trainer storytelling device 245. Likewise, the playgroup 230 ₂ also represents a science fiction-themed storytelling experience and includes a light sword controller storytelling device 260 and an action figure storytelling device 265. More generally, however, the playgroups may contain any number of storytelling devices of any number of different themes and types.

Generally, the playgroups 230 include storytelling devices within a particular physical location (e.g., a room of the house environment 225). That is, it may be preferable for a storytelling experience to only interact with storytelling devices within its immediate physical proximity (e.g., within the same room), as to do otherwise can potentially create security and other problems during the storytelling experience. A number of different techniques may be used to determine which storytelling devices are within immediate physical proximity of one another. For example, one or more of the storytelling devices could emit a first signal (e.g., an infrared signal) and the other storytelling devices could be configured to transmit a response (e.g., a radio frequency signal (RF)) upon receiving the first signal. The storytelling device(s) could then receive the responses from the other storytelling devices and could create a playgroup 230 that includes the other storytelling devices as well as the one or more storytelling devices.

Generally, it is advantageous for the first signal to be transmitted using a technique that does not readily pass through barriers such as the walls of a house (e.g., emitting infrared light), so as to detect only nearby storytelling devices that are within the same physical environment as the storytelling device. That is, while particular signals (e.g., RF signals) may be suited for inter-device communications, these signals may not be ideal for detecting nearby storytelling devices as they may readily permeate through barriers such as the walls of the house. Doing so helps to ensure that a storytelling experience will not make use of storytelling devices in different rooms of a residence or potentially within different residences altogether.

As shown, the devices 240 and 260 have been elected as controller devices within the playgroups 230 ₁₋₂. Generally, a controller device configures each of the storytelling devices within a playgroup to perform certain actions in response to a detected stimulus event and a current context of the story being told. Since acting as a controller device may result in more processing and data transmissions operations, serving as the controller device may also consume more battery power. As such, when two or more devices capable of serving as the controller device are present within a playgroup 230, embodiments can consider the current battery charge and battery capabilities of the capable devices when selecting one of the devices to serve as the controller.

As discussed above, devices can join and leave the playgroups 230 during the playback of a story. As such, the controller devices 240 and 265 can be configured to dynamically determine an optimal device(s) for the playback of a particular audio effect and can optimize the audio effect for playback on the determined device, based on the devices currently active within the respective playgroup 230. Doing so allows audio effects to be played back with the highest sound quality possible using the available devices, thereby enhancing the user experience during the story.

The story may include a number of different contexts in a temporal order, and the playback of the story may advance from one context to the next until the last context is reached and the storytelling experience is complete. However, while the story may be linear in progression, this is not necessary. For example, a story could have different branches, where the story can proceed down one of many possible arcs. For instance, arcs could be randomly selected, selected based on a user's request (e.g., the user specifying which arc should be taken), selected based on the user's actions (e.g., the user manages to “rescue” one of the fictional characters in the story), selected based on the user's history of actions (e.g., whether the user is trending towards the “evil side” in a science fiction storyline), and so on. Moreover, the story may be modified dynamically during playback based on various actions, such as one of the storytelling devices becoming unavailable (e.g., losing power, leaving the physical environment, etc.) or a new storytelling device being introduced to the environment (e.g., the user's friend comes over to play, bringing one or more new storytelling devices with him).

Additionally, the controller may maintain state information and control game logic for the playgroup 230. For example, playgroup 230 ₁ could be playing out a story in which a user is asked by the action figure device 240 to deflect virtual laser beams fired from the trainer device 245, using the light sword device 235. Here, the elected controller device (i.e., action figure 240) could maintain a “hit points” value for the user that is decremented when the user fails to deflect one of the virtual lasers, and could further maintain a count of how many virtual lasers the user has deflected thus far. Additionally, the controller could retrieve state data for the user (e.g., by querying one of the cloud-based services 215 with an identifier for the user) and could use the user state data to adjust the playback of the story.

In addition to detecting nearby storytelling device within the same physical environment, the storytelling devices within a playgroup 230 may elect one of the storytelling devices as a controller storytelling device. A number of different techniques may be used for such an election. For example, a user could explicitly specify that a particular one of the storytelling devices (e.g., the user's favorite device) should be used as the controller. It may be preferable for the user to select a device that will remain with the user throughout the storytelling experience, so as to avoid a subsequent controller election part-way through the story. In one embodiment, the controller may be elected based on technical specifications and properties of the storytelling devices. For example, a storytelling device with a substantial amount of memory, processing power and communication bandwidth may be preferable as the controller, relative to a device having a lesser amount of computing resources.

As discussed above, the story may generally include stimulus events and corresponding actions, and may be linear in progression or dynamic (e.g., a story that includes different story arcs or branches). In one embodiment, the story may be defined such that each corresponding action is attribute to a type or role of storytelling device (i.e., as opposed to a specific storytelling device). In mapping the story to the available and compatible storytelling devices, the controller device 220 could determine a type of each of the storytelling devices, and could assign particular stimulus events and corresponding actions to each of the storytelling devices based on the determined type. For example, a particular story could state that an action should be performed by a storytelling device having the role of “Hero”, and the controller could map the action onto a storytelling device within the playgroup having the role “Hero”.

For instance, assuming that the storytelling device 240 represents a first fictional character action figure, the controller 240 could assign any stimulus events and actions within the story that are specific to the fictional character to the action figure 240. Likewise, if the story includes any stimulus events and actions designated for a hero-type character in the science fiction universe, the controller 240 could assign these stimulus events and the corresponding actions to the device 240 as well. In the event multiple storytelling devices are available that satisfy the criteria for a stimulus event/action combination (e.g., multiple hero devices are present and available within the playgroup), the controller 240 could select one of the storytelling devices to perform each of the stimulus event/action combinations. The controller could use a number of different techniques for mapping the actions to the compatible devices, including a random mapping algorithm, a load balancing algorithm (e.g., round robin), user preferences (e.g., assigning more actions to a device the user has identified as his favorite), explicit user instructions (e.g., allowing a user to customize the story, such as selecting which character will narrate the story), and so on. In one embodiment, the controller is configured to consider the audio output and processing capabilities of the various compatible devices, when selecting one of the devices to perform a given action to a particular stimulus event. For example, when assigning a dialogue action to one of the devices, the controller could select a device capable of outputting the dialogue action with the greatest sound quality, in lieu of another device capable of outputting the dialogue with a relatively poor sound quality. Advantageously, dynamically mapping the story onto the available and compatible devices allows the story to be used with various different storytelling devices and combinations of storytelling devices.

In one embodiment, the story may specify a distinct, contextually appropriate action to perform for various types of storytelling devices for a given stimulus event. That is, the controller could determine that a particular story includes a stimulus event designated for a hero character, and could specify a corresponding action designated for a action figure 240 and a separate, distinct action designated for an different hero character-based device. In such an embodiment, upon selecting one of the devices to respond to the stimulus event, the controller could assign the corresponding action to the device based on the device's type. Doing so helps to create a more immersive and realistic storytelling experience for the user, as the storytelling devices can be configured to react to stimulus events in a manner appropriate for the represented fictional character.

Once the controller maps the story onto the devices, the controller configures each of the storytelling devices with a number of stimulus events and corresponding effects relating to a first context of the story. As an example, the action figure 240 could detect when the user has successfully deflected a virtual laser fired from the storytelling device 245 (i.e., an occurrence of the stimulus event), and could audibly congratulate the user in response (i.e., performing the corresponding effect).

In some cases, the controller (e.g., controller device 240) can map a particular audio effect to multiple devices for playback. The playback on the multiple devices can be done in unison or by using a time delay across the various devices. For example, a slight time delay could improve the sound quality of a particular audio effect by avoiding phase cancellation of the audio output by the various devices. By doing so, the controller can achieve a stereoscopic or surround sound effect.

FIG. 3 illustrates a physical environment including storytelling devices and a user, according to one embodiment described herein. For example, the storytelling devices can be electronically controlled in an automated fashion to carry out actions as part of an interactive game. As shown, the environment 300 includes a user 310 surrounded by a number of storytelling devices 315, 320, 325 and 335 as well as a control device 335. Generally, the control device 335 can select two or more of the devices 315, 320, 325 and 330 to output a particular sound and can generate a schedule by which the selected devices should output the sound. For instance, such a schedule could specify that the selected devices should output the sound in unison or could specify that each of the selected devices should output the sound effect at a different point in time, so as to introduce a time delay between the audio output of each device.

For example, a particular story having a jungle theme could include ambient sound effects that simulate the sounds of a jungle, including birds chirping, insects buzzing, the sound of a distant waterfall, and so on. In outputting the ambient sound effects, the control device 335 could distribute the various sound effects across the devices 315, 320, 325 and 330 (with some potentially output by the control device 335 itself) and could generate a timing schedule by which the various sound effects should be played by the devices 315, 320, 325 and 330. For example, the schedule could specify that the sound effects should be temporally staggered (i.e., not all played at the same time) and could distribute the sound effects across the devices 315, 320, 325 and 330, so as to create a three-dimensional soundscape for the user 310.

Additionally, as discussed above, the control device 335 can consider the individual audio playback and processing capabilities of the devices 315, 320, 325 and 330 when distributing the sound effects, so as to optimize the distribution of the sound effects to the most appropriate device 315, 320, 325 and 330. For example, a first sound effect could correspond to the beat of jungle drums and could include significant low frequency sounds, while a second sound effect could correspond to the sound of a distant waterfall and includes primarily medium frequency sounds. As such, the control device 335 could assign the sound effect of the drum beat to one of the devices 315, 320, 325 and 330 having audio output capabilities best suited to playing low frequency sounds, and could assign the waterfall sound effect to a device with more limited audio playback capabilities that is better capable of playing the primarily mid-range sound effect. Advantageously, doing so allows the control device 335 to optimize the assignments of the individual devices when creating the soundscape for the user 310.

In one embodiment, the control device 335 is configured to consider the position of the user 310 relative to the position of the devices 315, 320, 325 and 330, when distributing and scheduling sound effects to the various devices 315, 320, 325 and 330. For instance, assume that a particular story takes place within a bee hive and includes ambient sound effects simulating bees flying all around the user 310. The controller 335 could consider the user's 310 position in distributing the ambient sound effects to the devices 315, 320, 325 and 330 for playback, so as to ensure the output of the sound effects creates an immersive and three-dimensional soundscape for the user. Thus, in this example, the controller 335 could schedule the sound of a bee buzzing to be output by each of the devices 315, 320, 325 and 330 with a time delay in between each output, so that the sound of the bee appears to repeatedly encircle the user 310 who is positioned roughly in between all of the devices 315, 320, 325 and 330.

Moreover, the controller 335 can be configured to dynamically update the playback schedule and the devices used in the playback in real-time, as the position of the user 310 and the various devices changes. For instance, as the devices move throughout the physical environment (e.g., when carried by a user, when moving on their own, etc.), the controller 335 could dynamically update the playback schedule of the bee buzzing sound effect to maintain the effect of the sound encircling the user 310. For example, a first sequential playback order for the bee buzzing sound effect could be devices 315, device 320, control device 335, device 330 and then device 325, which could repeat indefinitely provided the devices 315, 320, 325, 330 and 325 and the user 310 remain in their depicted positions. However, if as part of the story playback the devices 315 and 330 move throughout the physical environment and change positions, the control device 335 could update the sequential playback order to be device 330, device 320, control device 335, device 315 and then device 325.

In addition to coordinating the devices 315, 320, 325, and 330, the control device 335 could receive sensor data collected by the movement tracking device 340 and the microphone device 345. The control device 335 could then perform one or more in-game actions within the interactive, based on the received sensor data. Of note, while the movement tracking device 340 and the microphone device 345 are shown as separate devices, in other embodiments the devices 315, 320, 325, and 330 may be configured with the movement tracking devices and the microphone devices.

For example, the control device 335 could determine a first interactive game is playing within the physical environment using the devices 315, 320, 325 and 330. For example, the control device 335 could be configured to recognize a plurality of distinct interactive games and could determine a unique identifier for a particular interactive game that is currently playing within the environment 300. The control device 335 could retrieve a game profile corresponding to the particular interactive game, describing a sequence of events triggering conditions, and storyline branches, within the interactive game.

The control device 335 could monitor user movement using the movement tracking device 340 within the physical environment. In one embodiment, movement tracking device 340 comprises one or more camera devices deployed within the environment 300. As another example, the movement tracking device 340 could represent a wearable sensor device that communicates the user's movement to the control device 335. For example, the wearable sensor device could include an inertial measurement unit (IMU) that includes one or more accelerometer devices, gyroscope devices and magnetometer devices. Additionally, the control device 335 could monitor user speech using one or more microphone sensor devices within the physical environment.

Upon determining that the user movement matches a predefined series of user actions and that the user speech matches a corresponding predefined speech pattern, the control device 335 could determine a gameplay action corresponding to both the predefined series of user actions and the predefined speech pattern. The control device 335 could then transmit an instruction, to at least one of the one or more electronic devices within the physical environment, instructing the electronic device to perform the determined gameplay action.

Generally, an interactive game can be composed of a variety of different contexts, and for each context, the control device 335 can be configured to control the interactive devices within the environment in different ways, responsive to different stimulus events. For instance, the control device 335 could be configured to initiate performance of a first set of device actions by devices 315, 320, 325 and 330, responsive to detecting a first set of user speech and actions using movement tracking device 340 and microphone device 345 during a first context within the interactive game, and the control device 335 could be configured to initiate performance of a different set of device actions by devices 315, 320, 325 and 330, responsive to detecting the same set of user speech and actions were performed during a different context within the interactive game.

An example of such an interactive game is shown in FIG. 4, which is a block diagram illustrating a composition of an interactive game, according to one embodiment described herein. As shown, the interactive game 400 includes contexts 410(1)-(N), where each of contexts 410(1)-(N) contains a respective plurality of gameplay actions 420. Each gameplay action 420 specifies a respective predefined speech pattern 430 and a predefined set of user actions 440 that, when detected, indicate that the corresponding gameplay action 420 should be performed.

As an example, during a particular context 410 within the interactive game 400, the control device 335 could detect the user has performed a particular gameplay action (e.g., a spell ability) within the interactive game 400 by performing a predefined set of user actions 430 (e.g., a twirling motion) and user speech 440 (e.g., speaking a certain phrase), and in response, could determine a corresponding gameplay action 420 to perform based on a current context 410 of the interactive game. For instance, the control device 335 could determine that the detected user speech and actions correspond to a frost spell within the interactive game and could initiate performance of the corresponding spell within the interactive game. Generally, the performance of the gameplay action 420 can have any suitable effect within the interactive game 400. Examples of such effects include, without limitation, dealing damage to a particular virtual character within the interactive game 400, adding a status effect to a particular virtual character within the interactive game 400, completing a quest within the interactive game 400, and so on.

Generally, the same set of user speech pattern 430 and user actions 440 can correspond to different gameplay actions 420 across various contexts 410(1)-(N) within the interactive game. For instance, the control device 335 could be configured with a transformation spell gameplay action that corresponds to a user action of twirling a wand and a user speech pattern of speaking the phrase “Allakhazam!” at a first context of the interactive game 400, and the control device 335 could be configured with a frost spell gameplay action that corresponds to the same user action of twirling the wand and the same user speech pattern of speaking the phrase “Allakhazam!” at a different context of the interactive game 400. Doing so enables the control device 335 to respond in a contextually appropriate manner to the user's behavior during the interactive game 400.

FIG. 5 is a flow diagram illustrating a method of controlling an electronic device, according to one embodiment described herein. As shown, the method 500 begins at block 510, where the control device 335 detects a first interactive game is playing within the physical environment. For example, the interactive game could be selected, from a plurality of distinct interactive games, using a graphical user interface provided by an electronic device (e.g., an augmented reality headset device). As another example, the interactive game could be selected by analyzing user speech data to determine a unique identifier corresponding to the interactive game. For instance, the user could speak the phrase “I want to practice my training exercises” and logic on the control device 335 could analyze the user speech data collected by the microphone device 345 to identify the interactive game to play (e.g., a predefined interactive game corresponding to the identifier “training exercises”). As yet another example, the control device 335 could transmit an instruction(s) to an augmented reality headset device, causing the augmented reality headset device to display an interface showing multiple interactive game titles, and the control device 335 could determine the user selection by analyzing movement tracking data collected by the movement tracking device 340 (e.g., by determining that the user touched an area corresponding to one of the interactive game titles.) More generally, however, any technique for selecting an interactive game can be used, consistent with the functionality described herein.

The control device 335 further monitors user movement within the physical environment using at least one sensor device (block 520). For example, the control device 335 could collect image data specifying images captured using a plurality of camera sensors within the physical environment and could analyze the image data to identify pixels representing the user within the images. The control device 335 could then determine the movement of the user by comparing the pixels representing the user within temporally adjacent images to determine changes between the pixels. As another example, the control device 335 could collect sensor data from a device held by the user, and could determine the user's movement based on the collected sensor data. For instance, the control device 335 could receive accelerometer data from a device held by the user and could process the accelerometer data to determine the user's movement. As yet another example, the control device 335 could receive electromyography (EMG) sensor data from an EMG sensor device worn by the user, and could analyze the EMG sensor data to determine the muscle movement of the user. While the above examples are provided for illustrative purposes only and without limitation, more generally any technique for determining the user's movement can be used, consistent with the functionality described herein.

The control device 335 also monitors user speech within the physical environment using at least one microphone device (block 530). For instance, the control device 335 could collect user speech data from one or more microphone devices 345 within the physical environment. As an example, a microphone device 345 could collect the user speech data and could transmit the user speech data to the control device 335 (e.g., using a wireless communications network).

The control device 335 then determines that the user movement matches a predefined series of user actions and the user speech matches a predefined speech pattern (block 540). The control device 335 then determines a gameplay action corresponding to the predefined series of user actions and the predefined speech pattern (block 550). For instance, the control device 335 could be configured to recognize a plurality of predefined user action and user speech patterns, and could be further configured with a mapping of each of the plurality of predefined user action and user speech patterns to a respective gameplay action.

The control device 335 transmits an instruction to one or more electronic devices, instructing the device(s) to perform the gameplay action (block 560) and the method 500 ends. For example, the control device 335 could transmit a data packet(s) over a wireless data communications network specifying a series of device movement operations to be performed, and control logic within the electronic device (e.g., one of interactive devices 315, 320, 325 and 330) could execute the series of device movement operations to control the movement of the electronic device (e.g., by actuating a motor(s) within the device to control one or more limbs of the device). Additionally, the data packet(s) could specify to output a digital audio file for playback using one or more speaker devices. For instance, the control device 335 could stream the digital audio file to the electronic device for playback, e.g., the data packet(s) could contain the digital audio file and, upon receiving the data packet(s), the control logic within the electronic device could output the digital audio file for playback. As another example, the control device 335 could transmit the data packet(s) specifying a unique identifier that corresponds to a particular digital audio file stored on a memory of the electronic device, and the control logic within the electronic device could retrieve and output for playback the particular digital audio file stored on the memory of the electronic device responsive to receiving the data packet(s) specifying a unique identifier. More generally, any gameplay action capable of being performed by an electronic device can be performed, consistent with the functionality described herein.

FIG. 6 is a flow diagram illustrating a method of controlling an augmented reality device, according to one embodiment described herein. As shown, the method 600 begins at block 610, where sensor devices within a physical environment monitor user movement, and further monitor user speech within the physical environment (block 615). At block 620, the sensor devices then transmits the collected sensor data to the controller device (e.g., control device 335).

The control device determines a current context of an interactive game (block 625) and determines a plurality of gameplay actions available for the current context of the interactive game (block 630). For example, the interactive game could be divided into a plurality of different contexts, where each context includes a respective set of gameplay actions mapped to corresponding user actions and speech patterns. Upon determining that the sensor data received from the sensor devices matches one of the sets of user actions and speech pattern corresponding to a first gameplay action (block 640), the control device transmits an instruction(s) determined based on the first gameplay action to an augmented reality device (block 645). Examples of the augmented reality device include, without limitation, a mobile device executing an augmented reality application, an augmented reality headset with a dedicated display device, an augmented reality headset configured to couple to a mobile device, and so on. More generally, the augmented reality device represents any device capable of providing an augmented reality display, consistent with the functionality described herein.

Upon receiving the instruction, logic on the augmented reality device (e.g., an augmented reality application) renders a plurality of frames depicting the first gameplay action (block 650) and outputs the frames for display using a display device (block 655), and the method 600 ends. For example, in a particular context of an interactive game, a user could be tasked with performing a wand gesturing motion and speaking the word “Allakhazam!” Upon detecting that the user has successfully performed the motion (e.g., by comparing sensor data describing the user's movement with predefined movement data corresponding to the wand gesturing motion), and upon further determining that the user has spoken the word “Allakhazam!” (e.g., by performing a speech to text analysis on sensor data captured using a microphone device within the physical environment), the control device could determine that the corresponding gameplay action (in this example) is casting a particular spell within the interactive gaming environment. The control device could then transmit an instruction to the augmented reality device, specifying to perform an effect(s) corresponding to the casting of the particular spell. Upon receiving the instruction, logic for the augmented reality device could retrieve predefined graphic effects data corresponding to the cast of the particular spell from a memory of the augmented reality device, and could render a series of frames depicting the spell being cast using the predefined graphic effects data. Additionally, the logic for the augmented reality device could retrieve predefined sound effect data corresponding to the cast of the particular spell from the memory of the augmented reality device and could output the predefined sound effect data using one or more speaker devices of the augmented reality device. Doing so creates an immersive environment for the user and provides dynamic, real-time feedback to the user's speech and behavior within the interactive game.

Technical Description

An example of an interactive device is shown in FIG. 7, which is a block diagram illustrating an interactive device configured with an interactive object component, according to one embodiment described herein. In this example, the device 700 includes, without limitation, a processor 710, storage 715, memory 720, audio input/output (I/O) device(s) 735, a radio-frequency (RF) transceiver 740, a camera device(s) 745, an infrared transceiver 750, an accelerometer device 755, and a light-emitting device 760. Generally, the processor 710 retrieves and executes programming instructions stored in the memory 720. Processor 710 is included to be representative of a single CPU, multiple CPUs, a single CPU having multiple processing cores, GPUs having multiple execution paths, and the like. The memory 720 is generally included to be representative of a random access memory. The radio-frequency transceiver 740 enables the interactive object component 725 to connect to a data communications network (e.g., wired Ethernet connection or an 802.11 wireless network). As discussed above, the interactive device may include one or more battery devices (not shown).

Further, while the depicted embodiment illustrates the components of a particular interactive device, one of ordinary skill in the art will recognize that interactive devices may use a variety of different hardware architectures. For instance, in one embodiment the controller component logic is implemented as hardware logic. Examples of such hardware logic include, without limitation, an application-specific integrated circuit (ASIC) and a field-programmable gate array (FPGA). Moreover, it is explicitly contemplated that embodiments may be implemented using any device or computer system capable of performing the functions described herein.

Returning to the embodiment depicted in FIG. 7, the memory 720 represents any memory sufficiently large to hold the necessary programs and data structures. Memory 720 could be one or a combination of memory devices, including

Random Access Memory, nonvolatile or backup memory (e.g., programmable or Flash memories, read-only memories, etc.). In addition, memory 720 and storage 715 may be considered to include memory physically located elsewhere; for example, on another computer communicatively coupled to the interactive device 700. Illustratively, the memory 720 includes an interactive object component 725 and an operating system 730. The interactive object component 725 could be configured to receive commands (e.g., encoded in RF or infrared signals) and to execute the commands to perform audiovisual effects. In one embodiment, the interactive object component 725 is configured to decrypt the commands using a received key before executing the commands. The operating system 730 generally controls the execution of application programs on the interactive device 700. Examples of operating system 730 include UNIX, a version of the Microsoft Windows® operating system, and distributions of the Linux® operating system. Additional examples of operating system 730 include custom operating systems for gaming consoles, including the custom operating systems for systems such as the Nintendo DS® and Sony PSP®.

The infrared transceiver 750 represents any device capable of sending and receiving infrared signals. In another embodiment, a device 700 that only sends or receives infrared signals may be configured with an infrared transmitter or a infrared receiver, respectively, as opposed to the infrared transceiver 750. The sound I/O devices 735 could include devices such as microphones and speakers. For example, the speakers could be used to produce sound effects (e.g., explosion sound effects, dialogue, etc.) and/or to produce vibration effects.

Generally, the interactive object component 725 provides logic for the interactive device 700. For example, the interactive object component 725 could be configured to detect that a coded infrared signal has been received (e.g., using the infrared transceiver 750). The interactive object component 725 could then determine a type of the infrared signal (e.g., based on data specified within the coded infrared signal) and could determine a corresponding response based on determined type. For example, the interactive object component 725 could determine that the infrared signal specifies that a ray blast sound effect should be played, and, in response, could output the specified sound effect using audio I/O devices 735. As another example, the signal could be encoded with data specifying that a particular lighting effect should be displayed according to a specified schedule (e.g., at a particular point in time), and the interactive object component 725 could monitor the schedule (e.g., using an internal clock) and could activate the appropriate light-emitting device 760 at the appropriate time.

FIG. 8 illustrates an example of a controller device, according to one embodiment described herein. As shown, the controller 800 includes a processor 810, storage 815, memory 820, a radio-frequency transceiver 840 and an infrared transceiver 845. Generally, the processor 810 retrieves and executes programming instructions stored in the memory 820. Processor 810 is included to be representative of a single CPU, multiple CPUs, a single CPU having multiple processing cores, GPUs having multiple execution paths, and the like. The memory 820 is generally included to be representative of a random access memory. The radio-frequency transceiver 840 enables the controller device 800 to transmit and receive radio-frequency signals. Likewise, the infrared transceiver 845 allows the device 800 to transmit and receive infrared signals. Further, while the depicted embodiment illustrates the components of a particular controller device 800, one of ordinary skill in the art will recognize that interactive objects may use a variety of different hardware architectures. Moreover, it is explicitly contemplated that embodiments may be implemented using any device or computer system capable of performing the functions described herein.

The memory 820 represents any memory sufficiently large to hold the necessary programs and data structures. Memory 820 could be one or a combination of memory devices, including Random Access Memory, nonvolatile or backup memory (e.g., programmable or Flash memories, read-only memories, etc.). In addition, memory 820 and storage 815 may be considered to include memory physically located elsewhere; for example, on another computer communicatively coupled to the controller device 800. Illustratively, the memory 820 includes a controller component 825, user data 830 and an operating system 835. The operating system 835 generally controls the execution of application programs on the controller device 800. Examples of operating system 835 include UNIX, a version of the Microsoft Windows® operating system, and distributions of the Linux® operating system. Additional examples of operating system 835 include custom operating systems for gaming consoles, including the custom operating systems for systems such as the Nintendo DS® and Sony PSP®.

Generally, the controller component 825 configures the interactive objects (e.g., toys 110, 115 and 120, or an action disc device 200) to perform particular actions. The particular actions can also be based on the user data 830 (e.g., historical interactions data between the user and various interactive objects, user preferences data, etc.) and one or more environmental factor (e.g., a room of the house the object is currently in, a time of day, a day of the week, etc.). For instance, in one embodiment, the controller component 825 is configured with logic for recognizing particular events and broadcasting commands for the devices to perform a corresponding action(s) in response. In such an embodiment, the controller component 825 could use input/output devices (e.g., cameras, microphones, wireless transceivers, infrared sensors, etc.) to detect when a particular event occurs. For instance, the controller component 825 could use a camera to detect when a particular projection appears, and could then broadcast a command (e.g., using a RF signal) instructing the devices to perform a corresponding action in response. As another example, the controller component 825 could receive a wireless signal (e.g., an RF signal, data communicated using Bluetooth communications, etc.) from another one of the devices, indicating that a particular action has been performed. The device could then broadcast a signal instructing one or more other devices to perform a corresponding action responsive to receiving the signal.

In a particular embodiment, the controller component 825 is configured to control the actions of multiple devices to cause the devices to perform audiovisual effects synchronously. For instance, the controller component 825 could broadcast a message to the devices, instructing the devices to perform a particular audiovisual effect immediately upon receiving the message. As another example, the controller component 825 could broadcast a message to the devices, instructing the devices to perform actions (e.g., play a sound effect, trigger a lighting effect, etc.) according to a schedule. Here, the devices may maintain internal clocks that are synchronized with one another for use in synchronously performing the audiovisual actions.

As discussed above, the controller component 825 can be configured to dynamically optimize the playback of audio on various interactive devices used in the playback of the story. Such alterations can include, without limitation, variable bit rate encodings of audio files, generating audio data using MIDI control operations, applying equalization parameters to alter audio data, scheduling multiple devices to output sound effects according to a schedule to give the impression of stereophonic or surround-sound, and so on. Doing so helps to provide a more immersive soundscape during the playback of a story.

Generally speaking, the devices and the controller 800 may be implemented in any number of different ways, consistent with the present disclosure. With respect to hardware, embodiments may employ a modular design for maximum hardware reusability across different interactive objects. Such a design could include, for instance, hardware adapters that allow common processors, memories and buses to receive and send data via a multiplicity of sensors, displays, effectors and other means of communication. Additionally, system and/or operating system agnostic sites (e.g., Portals) could be used to ensure maximum compatibility for all users.

FIG. 9 is a block diagram illustrating a mobile device, according to one embodiment described herein. In this example, the mobile device 900 includes, without limitation, a processor 902, storage 905, memory 910, I/O devices 920, a network interface 925, camera devices 930, a display devices 935 and an accelerometer device 940. Generally, the processor 902 retrieves and executes programming instructions stored in the memory 910. Processor 902 is included to be representative of a single CPU, multiple CPUs, a single CPU having multiple processing cores, GPUs having multiple execution paths, and the like. The memory 910 is generally included to be representative of a random access memory. The network interface 925 enables the augmented reality device 900 to connect to a data communications network (e.g., wired Ethernet connection or an 802.11 wireless network). Further, while the depicted embodiment illustrates the components of a particular mobile device 900, one of ordinary skill in the art will recognize that augmented reality devices may use a variety of different hardware architectures. Moreover, it is explicitly contemplated that embodiments of the invention may be implemented using any device or computer system capable of performing the functions described herein.

The memory 910 represents any memory sufficiently large to hold the necessary programs and data structures. Memory 910 could be one or a combination of memory devices, including Random Access Memory, nonvolatile or backup memory (e.g., programmable or Flash memories, read-only memories, etc.). In addition, memory 910 and storage 905 may be considered to include memory physically located elsewhere; for example, on another computer communicatively coupled to the augmented reality device 900. Illustratively, the memory 910 includes an augmented reality component 913 and an operating system 915. Generally, the augmented reality component 913 represents software that, when executed, generates frames representing an augmented reality display of the proximate physical environment, for output using the display device 935. The operating system 915 generally controls the execution of application programs on the mobile device 900. Examples of operating system 915 include UNIX, a version of the Microsoft Windows® operating system, and distributions of the Linux® operating system. Additional examples of operating system 915 include custom operating systems for gaming consoles, including the custom operating systems for systems such as the Nintendo DS® and Sony PSP®.

The I/O devices 920 represent a wide variety of input and output devices, including displays, keyboards, touch screens, and so on. For instance, the I/O devices 920 may include a display device used to provide a user interface. As an example, the display may provide a touch sensitive surface allowing the user to select different applications and options within an application (e.g., to select an instance of digital media content to view). Additionally, the I/O devices 920 may include a set of buttons, switches or other physical device mechanisms for controlling the mobile device 900. For example, the I/O devices 920 could include a set of directional buttons used to control aspects of a video game played using the mobile device 900.

FIG. 10 is a block diagram illustrating an augmented reality headset device, according to one embodiment described herein. The augmented reality headset device 1000 includes a mobile device adapter 1010, a beam splitter 1020, a sound adapter 1030, a see-through mirror 1040 and a head strap 1050. Generally, the augmented reality headset device 1000 is adapted to couple with the mobile device 900 to provide an augmented reality display for users wearing the augmented reality headset device 1000.

For example, the mobile device adapter 1010 could be a slot within the augmented reality headset 1000. The beam splitter 1020 and see-through mirror 1040 are generally arranged in such a way as to project light from the display device of the mobile device 910 to the user's eyes, when the user views the physical environment while wearing the augmented reality headset 1000. Generally, any configuration suitable for providing an augmented reality display using the light from the display device of the mobile device 910 can be used, consistent with the functionality described herein. The headstrap 1050 generally is used to secure the augmented reality headset 1000 to the user's head. More generally, however, any mechanism (e.g., temples that rest atop the user's ears) for securing the augmented reality headset 1000 can be used.

FIG. 11 is a block diagram illustrating an interactive object, according to one embodiment described herein. As shown, the interactive object 1100 includes a computer processor 1110, storage 1115, memory 1120, audio I/O devices 1135, an RF transceiver 1140, camera devices 1145, an infrared transceiver 1150, an accelerometer device 1155 and a light-emitting device 1160. Generally, the processor 1110 retrieves and executes programming instructions stored in the memory 1120.

FIG. 12 is a diagram illustrating an augmented reality headset configured to interact with a mobile device, according to embodiments described herein. As shown, FIG. 12 depicts a mobile device 1210 and an augmented reality headset 1220. The augmented reality headset 1220 includes a headstrap 1230, mobile device adapter 1240, and a mirrored lens 1250. Generally, the mobile device 1210 is configured to couple to the augmented reality headset 1220 by inserting the mobile device 1210 into the mobile device adapter 1240. The mobile device adapter 1240 is configured to hold the mobile device 1210 with a desired position and orientation relative to a wearer of the augmented reality headset 1220. The light produced by the display device of the mobile device 1210 is then redirected so that the light can be seen by a wearer of the augmented reality headset 1220. For example, the light could pass through a beam splitter, reflect off the mirrored lens 1250 and into the user's eyes. Doing so enables objects displayed on the display device of the mobile device 1210 to appear as if present within the physical environment. Advantageously, by leveraging the hardware resources of the mobile device 910, the augmented reality headset 1220 can be sold at a reduced cost, relative to other augmented reality devices containing dedicated computer processors, display devices, and so on.

FIG. 13 illustrates an exemplary implementation of a compact augmented reality (AR)/virtual reality (VR) display device 1300 (“display 1300”), according to one embodiment. In display 1300, the display of the smartphone is downward facing. Light produced by the smartphone display 1320 is transmitted downward, and is partially transmitted through the beam splitter and partially reflected by the beam splitter 1340 toward the positive power see-through mirror 1330. The positive power see-through mirror 1330 may have any suitable reflectance, and the reflected light is directed toward the beam splitter 1340. The reflected light may have a focus between about 1 meter and optical infinity. The beam splitter 1340 again partially transmits the incident light to the eye of the viewer 1310.

Display 1300 provides several benefits. The beam splitter 1340 of the optical arrangement has an orientation away from the eye of the viewer 1310, which generally allows a more comfortable wear or use of the display 1300. The design of display 1300 also allows the focal length of the positive power see-through mirror 1330 to be significantly shorter, which reduces the overall size and weight of the optical arrangement. For example, the height of the optical arrangement (as viewed, top to bottom) may be on the order of two inches. Although not shown, the optical arrangement of display 1300 may be small enough that only a portion of the smartphone display 1320 is provided to the viewer (e.g., a portion of the display extends forward of the positive power see-through mirror 1330 and away from the viewer 1310).

In an alternative embodiment including a polarized display, the beam splitter 1340 may be a polarized beam splitter. The display may include a quarter-wave retarder having a vertical orientation (as shown) and disposed next to the positive power see-through mirror 1330. The polarized beam splitter 1340 with the serial combination of the quarter-wave retarder and positive power see-through mirror 1330 can be arranged such that most incident light of a first polarization (produced by the smartphone display 1320) is reflected by the polarized beam splitter, and most incident light of a second polarization (reflected by the positive power see-through mirror and transmitted through the quarter-wave retarder) is transmitted by the polarized beam splitter. In this way, losses are reduced at each incidence of the displayed light on the polarizing beam splitter (reflection and subsequent transmission).

Generally, although the positive power see-through mirror has a positive power, the mirror does not distort imagery or refocus the imagery as the thickness of the mirror is consistent. In other words, the positive power see-through mirror has reflective optical power but does not have a refractive optical power.

In some alternate embodiments of display 1300, a dichroic mirror may be substituted for the beam splitter. Generally, dichroic mirrors exhibit different transmission and/or reflection properties for different wavelengths of incident light. Furthermore, the particular spectral bandpass of the dichroic mirror can vary based on the incidence angle of the light. For example, display 1300 may include a triple-band dichroic mirror configured to reflect only those wavelengths corresponding to red, green, and blue (RGB) lights while transmitting all other wavelengths. Alternate implementations may use other color models.

In one embodiment, the beam splitter (and optionally, the positive power see-through mirror) include a surface coating reflects at one set of wavelengths while transmitting at other wavelengths. In one embodiment, light from the display is incident on the beam splitter at a 45° angle, providing a first kind of reflectance of the light toward the positive power see-through mirror. For example, the light at specific RGB wavelengths may be mostly reflected at the 45° incidence angle with the beam splitter. At a normal incidence with the beam splitter, the light at RGB wavelengths may be mostly transmitted through. The positive power see-through mirror reflects some or substantially all (e.g., depending on whether the mirror is includes the specific surface coating) the light at the RGB wavelengths. Display 500 may include additional optical element(s) to reorient the light reflected by the positive power see-through mirror such that the reflected RGB light has a normal incidence on the beam splitter and is mostly transmitted through.
